MudCube by Cubility

Cubility - Facilities and offices

Cubility’s head office is located in Sandnes, Norway

A major part of the oil and gas activity in the North Sea is operated from the Sandnes/Stavanger region

Cubility has immediate access to potential customers and technology partners as all larger international players have offices in this region

Cubility has office space capacity to expand into a full project execution organisation

In 2009 Cubility opened sales offices in Houston, USA and Aberdeen, UK for international presence

There are currently 17 employees in Sandnes, one in Aberdeen and one in Houston

Cubility has built a full scale test centre next to the head office in Sandnes

The test centre is a state-of-the-art centre which can simulate offshore conditions in a full loop

It consists of two cabins; one with a traditional shaker and one with a MudCube system in addition to tanks, pipes, heaters, pumps, a control room and accessories

In addition to testing the MudCube the test centre is also used as Cubility’s full scale development facility where new technologies and solutions are tested

The test centre is fully owned by Cubility

Commercial breakthrough with Maersk Drilling

Signed contract with Maersk Drilling Norge to install 3 MudCubes onboard the drilling rig Maersk Giant

Installation of the MudCubes was completed during summer 2012 according to plan and the rig was ready for operations in the start of 3Q 2012

The rig is for the 3 first wells after yardstay operated by Talisman Energy Norge AS and DONG E&P Norge AS. Equipment and installation partly funded by operators

Maersk Drilling, Dong E&P and Talisman Energy did not conduct any test of the MudCube, but relied on the detailed testing done by Statoil

Equipment delivery time of less than 3 months

Installation time of 1 month including new header box, ducting, electrical / automation work (Hirtshals, Denmark)

MudCube – Significant HSE benefits

Overview of HSE benefitsComments

A MudCube system has a range of HSE benefits that are hard to measure in dollars

No doubt that the system saves the operator significant costs related to workers health and use of safety equipment

Reduce risk of accidents

Compelling HSE benefits both related to safety, working conditions and environment

Health benefits:

Strong reduction of oil mist/vapor and chemical exposure

to personnel (confirmed from Maersk operations)

Elimination of vibration: No need for structural

reinforcement because of weight and structural low

frequency vibration (confirmed from Maersk operations)

Noise reduced to 75 dBA, well bellow recommended

NORSOK standard of 83 dBA (for 12 hours working day)

(confirmed from Maersk operations)

Environmental benefits:

Less mud discharge offshore

Less waste liability

MudCube – Remote operation and automatisation

Remote controlled operationsAutomatisation

The MudCube can be controlled and operated remotely due to camera, sensors and control system

Real-time monitoring

Drillers cabin

Company rep

Cube-lounge cabin ( control room )

MudCube allows for real-time monitoring and remote operation

Cameras installed inside the MudCube, allowing for visual monitoring process without moving away from control room

Operator panel connected via Ethernet to PLC for visualizing and controlling / monitoring of the process

Feedback from Maersk Giant

I went to get a coffee and brought it

back to the MudCube lounge

because this is the nicest place to

be

Roughneck

Using a conventional shaker, I have to add

premix to the mud all the time. Using the

MudCubes, the mud-weight are very consistent

and almost no premix has to be added

Derrickman

My mud-pumps are much better off

now using the MudCubes as there

are less particles in the mud

Derrickman

That revolution statement on your t-

shirt… That might just be the truth!

Driller

Do you make these cubes portable?

… Cause I want to bring them

everywhere!!

Mudengineer

We did not change screens (filter belts) except for

finer filter belts when required – when using normal

pretensioned shaker screens we often replace and

repair the screens (which also lead to the mud pump

wear and the built up in the suction strainer housing).

Senior Toolpusher

At the shaker area the most significant change was

the working environment. The area was more or less

without fumes and the noise level had decrease

considerably. The working area is cleaner due to less

removal and cleaning of shaker screens.

Senior Toolpusher

No conventional shaker would have

handled the sticky clay we currently

see in the 17 ½” section
